com.avaje.ebean.config.dbplatform.IdType
- All Implemented Interfaces:
- Serializable, Comparable<IdType>
-
public enum IdType
- extends Enum<IdType>
-
The types of Identity generation that can be defined.
Enum Constant Summary |
GENERATOR
Use an IdGenerator to generate the identity (prior to insert). |
IDENTITY
Use a Database Identity (autoincrement) to generate the identity. |
SEQUENCE
Use a Database sequence to generate the identity. |
Method Summary |
static IdType |
valueOf(String name)
Returns the enum constant of this type with the specified name. |
static IdType[] |
values()
Returns an array containing the constants of this enum type, in the order they are declared. |

IDENTITY
public static final IdType IDENTITY
-
Use a Database Identity (autoincrement) to generate the identity.
SEQUENCE
public static final IdType SEQUENCE
-
Use a Database sequence to generate the identity.
Note: Some databases support getGeneratedKeys with sequences and this then does not involve an extra statement to return the id.
GENERATOR
public static final IdType GENERATOR
-
Use an IdGenerator to generate the identity (prior to insert).
Note: There is a IdGenerator for UUID's and it is automatically assigned to id properties of type UUID.
values
public static IdType[] values()
-
Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
for (IdType c : IdType.values())
System.out.println(c);
-
- Returns:
- an array containing the constants of this enum type, in the order they are declared
valueOf
public static IdType valueOf(String name)
-
Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
-
- Parameters:
name
- the name of the enum constant to be returned.
- Returns:
- the enum constant with the specified name
- Throws:
IllegalArgumentException
- if this enum type has no constant with the specified name
NullPointerException
- if the argument is null
